CA IX |
Acetazolamide also inhibits hCA II with an IC50 of 130 nM[1].
?
Acetazolamide (Ace) is a small heteroaromatic sulfonamide that binds to various carbonic anhydrases with high affinity, acting as a carbonic anhydrase (CA) inhibitor[2].
?
Compared with the control group, the high Acetazolamide concentration (AceH, 50 nM), Cisplatin (Cis; 1 μg/mL) and Cis combined with the low Acetazolamide concentration (AceL, 10 nM) treatments significantly reduces viability of Hep-2 cells[2].
?
Treatment with the Acetazolamide/Cis combination significantly increases the expression levels of P53, as both AceL+Cis and AceH+Cis treatments result in significantly increased P53 protein expression levels compared with the control group. The Ace/Cis combination treatment significantly reduces the bcl-2/bax expression ratio, and increases the expression of caspase-3 protein, compared with the control group. AceL, AceH, Cis and AceL+Cis treatments significantly reduce the bcl-2/bax ratio compared with the control group[2].
?
Combined Ace and Cis treatment effectively promotes apoptosis in Hep-2 cells[2].
?
Combined treatment with Ace/Cis markedly decreases the expression of AQP1 mRNA in Hep-2 cells. Both AceH and AceL+Cis treatments decrease the expression of aquaporin-1 (AQP1) mRNA in Hep-2 cells compared with the control group[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
? Acetazolamide (40 mg/kg) and/or MS-275 treatment reduce expression of HIF1-α and CAIX in NB SH-SY5Y xenograft[3].
? Acetazolamide (40 mg/kg), MS-275 and Acetazolamide+MS-275 reduce expression of mitotic and proliferative markers in NB SH-SY5Y xenografts[3].? Acetazolamide (50 mg/kg; PO, for 3 days) significantly reduces the gonococcal load in the vagina of infected mice by 90%[6].

Effect of Acetazolamide, a CA inhibitor, on oxidation of PTEN by H2O2. HepG2 cells were pre-incubated in HCO3−-free media, supplemented with 0, 0.01, 0.1, 1, and 10 µM Acetazolamide, at 37 °C with 0.1% CO2 for 4 h. Then, they were changed to stimulation media with same components plus 0.5 mM H2O2. After 10 min, the reaction was terminated by NEM-containing lysis buffer. Western blot data with PTEN and β-actin antibodies are shown Acetazolamide considerably impeded PTEN oxidation in a dose-dependent manner.
